What can I do if I have body ordo and everything I do don't work.

If I have a body odor and I try everything what can I do?

What parts of your body?
If your armpits, all you can really do is scrub with a brush like a soft back brush, and lots of soap. Wipe under your arms with peroxide or any astringent during the day.
If your crotch, you may have an infection based on yeast or bacteria.
You can get yeast or bacteria anywhere on your body that is folded skin (underarms, navel, tops of legs) and that is called intertrigo, and is basically just like diaper rash in infants. Keep clean and dry and wear loose fitting natural fiber clothing. You can buy anti-bacterial cream in a drugstore, or a doctor can prescribe stronger creams.

Again, what have you done ? What part of the body ?

Many people have to bath at least twice a day and sometimes wash off in between. If a lot of hair, try shaving the hair in that area.

Next when and how, I play basketball, and will always have odor when done with that.
